This isn't just a string of pearls. We've broken up the strand of dark, lustrous freshwater pearls with solid gold beads, each one fully paved with natural diamonds. It's a contrast of textures you can see from across a room.

A long, 26-inch strand of near-round freshwater pearls. Their colour is a deep, iridescent grey with overtones of purple and blue that shift in the light. On each side, the string of pearls is broken by two spherical beads completely covered in small, pavé-set diamonds that catch and scatter light from every angle. The necklace hangs in a soft U-shape.

Those sparkling beads are solid 18 karat gold, which is 75% pure gold. We use 18k because it has a substantial heft and a rich colour that won't fade. The high gold content also means it's hypoallergenic and very unlikely to irritate sensitive skin. The pearls are freshwater, chosen for their dark, complex colours and nearly-round shape. The diamonds are natural, so they have the specific, fiery sparkle that only comes from a stone formed in the earth.

The 26-inch length gives this necklace a different feel from a classic choker. It drapes low on the chest, and depending on your frame, you might be able to loop it twice for a layered look. It's a way to wear pearls that feels more modern and less formal.
